Water is fundamental to all life on Earth. While it may be easy for many of us to take the availability of water for granted, growing demands on the world's water resources highlight the importance of water to everyday life. Access to clean water is a growing political issue around the world.
Recognition of Survival Needs
In 1977, basic survival needs were stressed at the Mar del Plata conference, a major international effort to address world water problems organized by the United Nations. The issue of the right to basic water needs was illustrated by the statement that "all people . . . have the right to have access to drinking water in quantities and of a quality equal to their basic needs."
As world populations grow, societies are challenged to provide clean water and sanitation services. Of significant concern is meeting basic human and ecological needs for water, vital for survival and good health. Many societies struggle to allocate sufficient resources to meet those needs for all of their people.
Absolute Minimum Requirements.
Water is required for the maintenance of life; researchers have investigated the absolute minimum amount of water required for human survival. Regular intake of water is needed to maintain a person's water balance, as water lost through normal activities must be restored. The minimum water requirement for replacement purposes, for an "average" person, has been estimated to be approximately 3 liters (3.2 quarts) per day, given average temperate climate conditions.
In addition to drinking requirements, water is traditionally used for sanitation purposes for the disposal of human waste. Effective waste disposal has many health benefits as it serves to control the spread of disease. Humans also have basic hygiene needs for personal washing and bathing, and for food preparation. These hygiene-related uses of water also have many health benefits.
Drinking, sanitation, and hygiene needs constitute the basic human survival needs for water. These minimum needs total about 50 liters (13.2 gallons) per person per day. In comparison, the average American uses well over ten times that amount. Fifty liters per person per day maintains a person's water balance and provides benefits vital for human health. In 2000, it was reported that 55 countries, with a combined population of over 1 billion, average below this basic level.
A Human Right to Water
Lack of safe water has significant costs to societies in terms of health costs, lost economic productivity, and human suffering. For example, 14,000 to 30,000 people die each day from water-related diseases; most of these deaths are children and elderly persons. Concerns over these losses and suffering have spurred considerations over a human right to water. Typically, one thinks of human rights as general freedoms and a response to violence, as outlined in the 1948 Universal Declaration of Human Rights. If the United Nations recognized water as a fundamental human right, countries would have a duty to protect and promote these rights: then international law, declarations, and state practice could support the provision of water services to all.
Many view universal access to basic water services as a fundamental condition for human and economic development. The overall lack of access existing around the world today is a failure of modern economic development efforts. The World Bank estimates that more than 1 billion people lack access to safe drinking water and over 3 billion live without access to adequate sanitation systems needed to reduce harmful water-related diseases.
Future Water Perspectives.
In November 2002, the United Nations Committee on Economic, Cultural and Social Rights issued a statement declaring access to water a human right. This recognition reflects the importance of water to human life and the ongoing challenges societies face in providing water for all their citizens.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
